Application filed June 25, 1920. Serial No. 391,626.

To all whom it may concern:

Be it known that I, DAVID EARL HARD- MAN, a citizen of the UnitedStates,and a resident of Simms, in the county of Gascade and State of.Montana, have invented certain new and useful Improvements inGrease-Cups, of which the followingis a specification.

My invention relates to grease cups, and a purpose of my invention istheprovision 0 a grease cup in which there are no screw threadedportions to be'removed when refilling the cup, thereby eliminating thatnuisance common tothe usual grease cup' of remeshing. the threads of onepart with those of another whenclosing the cup subsequent to the fillingoperation.

It is also a purpose of my invention to provide a grease cup having acap which is quickly and easily removed, and means asso- V ciated withthe cap for automatically locking the same against accidental displacement.

I will describe one form of grease cup embodying my invention and willthen point out the novel features thereof in claims.

In the accompanying drawings:

Figure 1 is. a view showing in sideeleva tion one form of grease cupembodying my invention. i

Fig. 2 is a vertical sectional view taken onthe line 2-2 of Fig. 1.

Fig. 3 is a sectional view taken on the line 33 of Fig. 1. i

Figs. 4 and 5 are detailed views showlng in perspective the containerportion and cap, respectively shown in the preceding views. 7

Similar reference characters refer to similar parts in each of theseveral views. I

Referring specifically V to the drawings, the grease cup essentiallyconsists of a base B having formed integral therewith a screw threadedstem S which is adapted to be fitted within the element to be lubricatedso as to'support the cup as a unit thereupon. Rotatably mounted upon thebase B is a container 0 which is adapted to receive and house the greaseto be dispensed. The container C has removably fitted thereon a cap Kwhich closes the upper end of the container, as will be understood. 7

As illustrated to advantage in Fig. 2, the base B and the stem S arebored axially thereof to provide a duct 15 through which lower edge ofthe grease from the container C is adapted to be ejected from the cup.The periphery of the base B is screw threaded, and similarly the innerwall of the container C is screw threaded to threadedly engage the base.The cap 'Kdoes not threadedly engage the container C but is providedwith means engageable with means uponthe container for securing the captotlie container and locking the same against accidental. displacementtherefrom. This means, in the PATENT: orator..- 1

present instance, comprisesa pair of flanges designated at Fv disposedat diametrically opposite points upon the periphery 'of the containerand arranged spirally. with respect to each other. As shown in Fig.4,

the widest end of each'of the flanges F is provided with a lug 16, andadjacent the 7 narrow end of each flange is ajnotch' 17. Arranged atdiametrically opposite points upon the cap-K and in depending relationthereto are a. pair of arms A of substantially U -shaped contour incross section.

These arms, as well as the flanges F, may be" formed integral with theirrespective members, the arms being adapted to engage V the flanges inthe manner shown in Figs.

' 1' and 12 sojthat when rotated in the direction of the widest. end of.the flanges the arms firmly. engage the same and thus se cure the cap inclosing position upon the upper end of the conta1ner,; it beingunderstood that thelugs 16 limit the movement ofthe arms into lockingposition; To prevent accidental disengagement of the arms from theflanges, a leaf spring R is pro-.

vided, 'which in the present instance, is shown as being formed integralwith one of the arms A and provided at its freeend with an inwardly benthook18 which,in

the applied position'of the cap, is adapted to engage either of thenotches 17 and to thereby lock the cap against rotation upon thecontainer. p I

As shown in Figs. 1 and2, the lower edge of the base B is beveled asindicated at 19,, thepurpose of which is to provide a surface againstwhich a pair of fingers G is adapted to abut for preventing displacementof'the container G from the base B. As shown'in' Figs. 3 andjfl, thefingers G areformed at diametrically opposite points upon the thecontainer and are bent inwardly toward theaxis of the container-so as toengage the beveled. edge 19 when the container is in its uppermostposition, thus preventing further rotation of the container to disengagethe base.

To insure the removal of all grease from the container and base,upstanding lips L are formed within the base in the shown in Figs. 2 and3, those lips serving to direct the grease to the upperend of the duct Twhen the container C is rotated. v

In operation, the cap K having been removed, and the container G screwedto its uppermost position, the latter is completely filled with grease.The cap K is now applied by positioning the same so that the arms AAwill be disposed between the flanges F -1 so that by rotating the cap ina clockwise direction, the arms will be caused'to engage the flanges inthe manner previously described, and when the arms have reacheda'securing position with respect to the flanges, the hook end :18 of thespring It automatically drops into one of the notches 17, thus lockingthe cap against accidental displacement. The cap 11 ving been applied,the cup is now ready for dis pensing of the grease, such operation beingeffected by a rotation of the container. downwardly upon the base, thusforcing the grease into the upper end of the duct and subsequently outof itslower end, as will be understood. 1

From the foregoing operation, it will be manifest that whenfilling thecup, the container C can be completely filled with grease and withoutanywaste thereof because the container, when in its up )ermost position,can be completely filled 'withoutlmaking any allowance for plunger. orother device found in theiusual grease cup for efiecting the ejectionof. the grease from the cup It will be further manifest that when thecontainer C is screwed to its lowermost position, the upper edge of thebase will engage the under side oft-he cap K, and under the action ofthe lips L, a complete ejection of the grease from the container iseffected.

Although I have herein shown and describedonly' one form" of grease cupembodying my invention, it is to be understood that various changes andmodifications may be made herein without departing from the spirit ofthe invention and the spirit and scope of the appended claims.

hat I claim is:

1. A grease cup comprising, a base, a container threadedly' engaging thebase, means for limiting the movement of the container on the base inone direction, a cap removablj fitted on the container and adapted tolimit the movement of the container in either direction, and means forlocking the cap on the container comprising, spirally arranged flangeson the'container having lugs on one end thereof and notches adjacentthe. other end, arms formed on the cap and engageable with the flanges,and a spring on one x i ot the arms adapted to engage OlGllQl ot saidnotches for loclnngthecap against rotation.

" 2. A grease cup comprising, a base, a stem "formediintegral with thebase, said stem and base being bored to provide a discharge duct,'a pairof upstanding lips formed in the base, a container threadedly mounted onthe base, fingers formed on the container,

said fingers depending from the lower edge of said container and beingbent'inwardly to engage said base when the containeris in apredetermined position, spirally arranged fianges formed' on theperiphery of the container adjacent its upper edge, a cap adapted toclo'sejtheupper end of said container, arms carried by said cap anden'gageable with said flanges for securing the cap to the container. andeoacting means formed on said container and capl'or locking the latteragainst accidental displacement from the container. v
